pendently of power actuated mechanism. De-

vices of this general class are usually constructed to serve thefunction of an emergency release to be operated manually in the eventthat the motor driven mechanism becomes stalled, such as due to a suddenbreak in the electrical circuit. The necessity of such a device, undersuch circumstances, will be apparent because it may happen that theelectrical current is broken at a time-when the ironing machine is inopera tion with the ironer shoe in cooperating engagement,with the roll,in ironing a piece of fabric or an article of apparel. In such case thefabric being ironed may be burned or damaged if means were not providedto manually back the shoe,

away from the roll. Another function of many commercial forms ofreleases of the character indicated, is to permit adjustment of the shoeto a position at which it may be swung about its mounting in an upwardlyopen horizontal position so that the ironing surface of the shoe may beemployed for performing certain special ironingoperationswhich areimpossible to perform with the shoe in normal cooperating en-- gagementwith the roll, such as in ironing of put? sleeves of a dress, pressingof neckties, etc.

One of the objects of this invention is to provide a novel and animproved form of release of the character indicated in which the controlhandle for actuating the release normally extends in an upward directionand is adaptable to be telescoped downwardly to render the total ironingmachine construction relatively compact and enabling it to be housed orenclosed within a cabinet of minimum dimensions.

Another object res des in the provision'of an improved release of thecharacter indicated having means associated therewith for varying theefiect ve pressure'of the shoe against the roll.

A further object resdes in the provision of an improved device of thecharacter indicated including means adapted for resiliently moving theshoe away from the roll when the device has been operated.

Still another object is to provide an improved release of the characterindicatedhaving an, up-

'wardly extending control handle adapted to be 'telescoped downwardly toa position for interlocking engagement with parts of the control devicefor precluding operation of the device.

A still further object is to provide an improved release of thecharacter indicated, having a manually operable control handle adapted,when the shoe is backed away from the roll, to swing the shoe about itssupport to dispose its operating surface in an upwardly facing directionfor per- 19 forming certain special ironing operations.

And a still further object of this invention is to provide an improveddevice of the character indicated which is simple in construction,positive in operation, easily accessible for manipulation, and capableof economical manufacture.

Other objects and advantages of the present invention will be apparentfrom the following description, taken in connection with theaccompanying drawings in which:

In the illustrated embodiment of my invention I have disclosed anironing machine of the folding type wherein the ironing mechanism isassociated with a cabinet in a manner which permits it to be foldedwithin the cabinet when not in use, or withdrawn into operating positionoutside of the cabinet, as, seen in Fig. 1 of the drawings. It will bemanifest, however, and as will be apparent from the followingdescription, that the present invention is not to be limited for usewith a folding type ironer, but isreadily adaptable to various othertypes of ironer units, such as a portable type, or table top ironerunits. Referring now in detail to the drawings, the reference characterIll indicates a cabinet of substantially rectangular box-like form, ofsubstantially greater height than width or depth for an ironer mechanismindicated generally at H, mounted on a baseboard or support I2, theironer mechanism and the baseboard being movable as a unit for foldingwithin the cabinet when not in use. The ironer mechanism comprises aroll I3 and a cooperating shoe l4, the former being totally supported atone end by a housing or standard i5 mounted on the inner end of thebaseboard l2, as seen in Fig, 1. The shoe I4 is of a conventionalconstruction and may be heated electrically. It is to be understood thatthe housing i5 contains suitabledriving and control mechanism forrotating the roll and for moving the shoe into and out of cooperatingrelation therewith, and said mechanism is driven by an electric motorhoused within a casing l8 secured to the under side of the baseboard ii.The motor includes an upwardly extending shaft I! to the upper end ofwhich is rigidly attached a driving pinion l8 meshed with a gear IS onthe lower end of a main vertically disposed drive shaft journaled insuitable bearings within the housing I5. Connected to the upper end ofthe main drive shaft 20 is a driving worm 2| operatively engaged with aworm gear 22, adapted for operable engagement with suitable driving andcontrol mechanism, such as of the type disclosed in my co-pendingapplication Serial No. 134,541 filed April 2, 1937. The mechanism withinthe housing I! as disclosed in said co-pending application is renderedoperable by a hand control lever 24 which serves normally upon oneactuation to move the shoe I 4, into operative engagement with the roll,and upon the next successive actuation to move the shoe back away fromthe roll. Said mechanism may be understood to be such as to normallycause rotation of the roll substantially when the shoe engages the same,and substantially'causes arresting of the roll at the time the shoecommences to back away from said roll. However, when it is desired thatthe roll remain stationary irrespective of the actuation of the shoe,the mechanism for driving the roll may be controlled by the handle 26which diseneages drive connections to the roll, as indicated in myco-pending application.

The cabinet I0 is provided with a door opening I! through which theironer unit passes when .it is moved into and-out of -.the cabinet.Suitable means is provided for guiding the ironer unit during suchmovement for causing folding of the unit in vertical position when ithas been moved completely into the cabinet and to unfold the same in ahorizontal. position as seen in Fig. 1 when entirely withdrawn from thecabinet. Although the mechanism for performing these functionsconstitutes no part of the present inven- 7 from the rails 28 by thestruts 32 and the outer end of the baseboard is supported by a foldablehinged leg 35 which may be collapsed against the under side of thebaseboard II when the ironer is disposed in folded position in thecabinet. The leg 35 is automatically folded during the movement of theironer into the cabinet and any suitable mechanism may be employed forthis pur-- pose. In the drawings this mechanism includes a link 36connected at one end to the leg, while the opposite end' is connected toa cam 31 which in turn is actuated by the link 30.

The roll I; is of a conventional construction including a tubularmetallic supporting body 40 around which is wrapped one or more layersof resilient material or padding 4| andwhich may be understood to becovered by an outer jacket or wrapper of suitable fabric such as muslin.Mounted in opposite ends of the tubular body 40 are dish-shaped elements43 having Journaled support on a stationary tubular sleeve 44 whichextends longitudinally and centrally in the tubular body and is rigidlyanchored at one end in the housing l5, providing journal support for theroll I3. Extending longitudinally through the tubular sleeve is a rolldrive shaft 46, one end of which extends into.the housing I! and isdetachably engaged by the driving mechanism in said housing, as abovereferred to, while the opposite end of said shaft extends through andbeyond the dished end plate 43, at the outer or unsupported end of theroll. Rigidly mounted on the outer end of the shaft 46 is a sleeve 41having a flange 4' rigidly attached to said end plate 4! so thatrotation of the drive shaft 48 is transmitted through the sleeve 41 andflange 4! to the element 43 for causing rotation of the roll.

The shoe I4 which cooperates with roll I! and is movable into and out ofengagement therewith is of elongated form and is of substantially thesame length as the roll, and the operating face of said shoe is curvedarcuately in cross-section to approximately the same curvature as theexterior surface of the roll. The shoe is supported adjacentitslongitudinal center by means comprising a bracket rigidly secured to theback of'the shoe and formed with a pair of rearwardly extending ears 5|Journaled on a pivot pin ll, the axis of which extends substantiallyparallel to-the roll IS, the pivot pin being carried in a pair of ears5! formed'on the upper end of an upwardly extending supporting arm I,the lower end of which arm is :lournaled on the end of a tubular rockshaft 54 which extends parallel to and below the axis of the roll I. Theother end of the rock shaft extends into a rearward portion isof thehousing 15. Surrounding the rock shaft is a tubular sleeve 55 rigidlysecured at one end in the housing portion l", while its opposite endterminates adjacent the arm 52 and is surrounded by a'bearing 56 of afoot bracket 56 secured to the top of the baseboard l2. Said footbracket 56 thus assists in supporting the shoe M, through the arm 52.Mounted in the opposite ends of the tubular sleeve 55 and surroundingthe rock shaft 5d are bushings or bearings 57 which serve to properlysupport the rock shaft centrally within the tubular sleeve.

Said housing It is formed with a tubular chamber i5 substantially radialto the axis of the roll and extending in a rearward and downwarddirection below the rock shaft 56 as seen in Fig. 3..Disposed within thechamber l5 is a bolt 58 having a head 58*, the under side of which isrecessed to form a pocket for the end of a compression spring 5Q,the'opposite end of which spring seats in a recess til of an actuatingblock 60 slidably mounted on the bolt and in the tubular chamber lt intowhich extends the end of an actuating block or finger t2 rigidly securedto the end of the tubular rock shaft 5d. The lower end of the bolt isreduced in cross section to provide a shoul der 58 against which isseated a washer 6d held in place by a nut 65, and places spring 59,under compression. The lower endof the chamber B5 is closed by athreaded cap $6 formed with a recess 66* to provide a seat for acompression coil spring 63 which circumscribes the lower end of the boltand abuts against the washer 8'3.

The upper end of the head 58* of the bolt is formed as a clevis 58 and aroller 69 is interposed between the ears of the clevis and journaied ona pin 69. The spring 59 normally tends to'urge the bolt 58, due to theengagement of finger 62 in the block til, in an upward direction so thatthe roller til is constantly in engagement with the periphery of aclover-leaf shaped cam 10, having three high portions iii? and threealternate low portions it". It is to be understood that upon'sucoessiveactuations of the controlling lever 28 the cam '70 is rotated one-sixthof a revolution to dispose either a high portion it or a low portion'i'il of said cam into cooperative engagement with the roller 69, asdisclosed in my said co-pending application. Thus when the cam it ismoving to a position as seen in Fig. 2, with the roller engaged with alow portion 'ltl of the cam, the force acting'on the compression spring59 is reduced and the coil spring $8 is free to move the bolt in anupward direction and through the block tit and finger 62 causes rockingof the tubular shaft 59. in a direction for swinging the supporting arm52 rearwardly, and moving the shoe M back, away from the roll.

When pressure is exerted against the roller 69 .by camming action due toreadjustment of the cam it, resulting from'the manipulation of thecontrol handle 2 so that a high point W of the cam aligns with theroller 69, as seen in Fig. 3, the bolt 58 is urged in a downwarddirection, and through the medium of the compression spring 59, theblock W is urged downwardly which through the finger 62 causes rockingof the shaft 54 forwardly, swinging the arm 52 in a direction to movethe shoe ifl into cooperative engagement with the roll, as seen in Fig.3. It is to be understood that the shoe. engages the roll prior to thehigh point 10 of the cam, fully actuating the bolt 58 through roller 69,and that The side wall of the block til is formed with a slot or opening6t about the pin 5 I J further downward movement of the bolt 58 ispermitted and the block 68 is urged against the finger 62 by the forceof the increased compression of the spring 59, as the high point it ofthe cam aligns with the roller 69, thus providing resilient pressure ofthe shoe against the roll for insuring proper. ironing or pressingoperations upon fabrics, such as indicated generally at A in thedrawings.

As above mentioned, it isv essential to provide some manual form ofrelease which will permit movement of the shoe away from the roll in theevent ofan emergency such as when electrical current is suddenly out offand the shoe is in cooperative engagement with the roll. In the presentinvention this release is directly associated with and is formed as apart of the support for the shoe on the rock shaft 5 3. The supportingarm 52 which as above mentioned is journaled at its lower end on the endof the rock shaft, is formed with a pair of axially spacedapart ears 52intermediate which is disposed a lever 72 surrounding the rock shaft 56and rig-' idly clamped thereto by a machine screw it engagingcooperating ends of the body of the lever, surrounding the shaft, asseen in the drawings. Said member l2 includes an arm 12 which extendsinto a recess or slot formed in the lower end of an upwardly extendingrod M which is slidably mounted in the body of the arm 52. The upper endof the rod carries a roller '85 journaled on a pin 56 on said rod, andco-acting with said roller is a cam lll, co-pivotally mounted on thepivot pin 5! with the ears 58 of the bracket 56. Said cam is formed withan upwardly extending boss ill to which is connected a manual controlhandle, including a rod 78 telescopically mounted in said boss andprovided at its outer end' with a knob it. The lower end of the rod 78is formed with an annular recess it which is adapted, when the controlhandle is withdrawn upwardly to operating position, to be aligned with adetent comprising a ball at and a pressure spring mounted in a recess Nof the cam. Said recess is disposed at an angle .so that the ball 86will definitely serve as a stop shoulder against the lower shoulderforming the groove w of the control rod in to positively precludewithdrawal of the control rod F8 from the cam, as may beseen in Fig. 2.The recess 78 is formed to provide a tapered portion 18*, whichconveniently depresses the detent when the control handle is telescopeoldownwardly into the cam, to a position as may be seen in Fig. 10.

The 'inner portion of the supporting arm 52 is formed with a body 52provided with a recess 52 in which is mounted a button 83 seated againsta compression spring 8 3, the button 83' being provided with 'an annularflange 83 The button is confined within the recess by an escutcheonplate 85 surrounding the button and rigidly attached to the body portion52. This spring-pressed button 83 normally engages the lower backportion of the shoe IQ and serves as a stop for arresting pivotalmovement of the shoe Said spring button also serves to assist inproperly maintainingv the shoe in proper relation on the roll l3 forexerting proper pressure in performing an ironing operation upon a pieceof fabric. heavy piece of fabric is being ironed and has passed beyondthe leading edge of the shoe, this button 83 will preclude the forwardorf-leading edge of the shoe from tilting forwardly or in- For example,if a relatively,

'wardly, which would reduce the pressure in ironing the final portion ofthe piece of fabric.

Resilient means is provided for normally urging the arm 52 rearwardlywith respect to the lever bracket 12 and in the drawings said means isshown in the form of a compression spring 86 enclosed within a tubularbody of a button 81, mounted in a recess 12 on said lever, with thespring reacting against the under side of the button and the bottom of arecess, urging the head of the button against the arm 52. Thisspring-pressed button serves to operatively move the arm 52 togetherwith the shoe [4 to the position seen in Fig. 4 when the cam 11 has beenadjusted to the position seen in Fig. 4 by operation of the controlhandle. This action takes place by reason of the fact that the lever I2remains stationary and the reactive forces against the temporarily fixedlever 12 caused by the spring pressed button 81, which may be understoodto be suillcient to overcomev the effect of gravity acting on the shoel4, moves the arm 52, rearwardly together with said shoe, causingrelative movement of the rod 14 with respect to said arm 52 so that theroller 15 is maintained in contact at all times with the operatingsurface of the cam 11. g

The operating surface of the cam includes three re-entrant portions 11,11 11. As may be seen in Figs. 2 and 3 when the portion 11 is inengagement with the,roller 15, the parts are in normal operatingcondltionso that the shoe It may be moved to and from cooperating en-'gagement with the roll l3 by the drive mechanism under control of thelever 24. However, when it is desired to actuate the emergency releasethe control handle is swung rearwardly to a position as seen in Fig. 4,at which time the cam 11, aligns the re-entrant portion 11 with theroller 15, permitting the arm 52 to swing rearwardly, by the springpressed button 81, carrying the pivot pin therewith, and withdrawing theshoe l4 back out of engagement with the roll, so as to permit removal offabric from between the shoe and roll, in the event that the ironerdrive mechanism is rendered inoperative, such as by breaking of thepower circuit. In such position of ad- Justment of the release device,cooperating abutment surfaces 11 of the cam 11 and 50 of the bracket 50are in engagement, as seen in Fig. 4, and further movement of thecontrol handle in a downward direction is limited by reason of the factthat the lower edge of the shoe will contact the surface of the roll.This feature is important in that it definitely precludes thepossibility of burning the wrist of the operator in reaching over theshoe and-operating the control handle for swinging the shoe to anupwardly 1 open position as seen in Fig. 5 for performing certainspecial ironing operations, such as irona garment, steaming of 7 ingruilies, pufl. sleeves of fabrics, etc. The release device may be resetby swinging the control handle in an upward direction to dispose thereentrant cam portion 11 in registration with the roller 15, which movesrod 14 downwardly and moving the arm 52 forwardly to dispose the shoe ina rearward position of adiustment.

' When it is desired to dispose the shoe in the Fig.';5,--the" shoeshould first be nism under control of lever Zlso that the shoe arrivesat a position indicated in dotted lines at B in Fig. 5. Then uponactuation of the release by shifting the control handle rearwardly foraligning reentrant portion 11 of the cam with the roller 15, the shoe ismoved rearwardly an additional amount to a position as indicated indotted line at C in Fig. 5. Now the operator may by moving around to theback of the machine grasp the control handle and swing it downwardly,and due to the abutment stops 1'! and 50 of the cam and shoe bracketrespectively, the shoe may be further rocked about the pivot pin 5| tothe upwardly open position as seen in Fig. 5 at which position the shoebecomes arrested by engagement pf stop shoulders 51'! on the respectiveears 50 of the bracket 50, engaging the surface of the arm 52 as seen inFig. 6 of the drawings, and the reentrant portion 11 of cam 11 is seatedon the roller 15, tending to maintain the parts in such position ofadjustment. It will be apparent that if desired, when the shoe is backedaway from the roll by the power driven mechanism, the operator may byone continuous swing of the control handle back the shoe away from theroll an additional amount and rock the shoe to an upwardly facingposition as seen in Fig. 5. The release may be quickly reset by merelyswinging the control handle upwardly to register reentrant portion 11 ofthe cam with the roller 15, and disposing the shoe in a normal to theroll. In other words, if the screw 90 is. threaded upwardly, asubstantial distance and thereby raising the rod 14, the effectivepressure of the shoe on the roll will be increased, and by withdrawingthe screw so as to permit the rod 14 to move downwardly with respect tothe lever arm 12*, the effective pressure of the shoe on the roll isreduced. The screw 90 is maintained in any position of adjustment by acoil spring 81 reacting between the head of the, screw and the underside of lever arm 12". This is an important feature in that it permitsan operator to make quick and easy adjustment of pressure to suitdesired ironing conditions.

The body of the arm 52 just above the spring button 83 formed with anintegral strap or socket 52 for receiving the lower end of the rod 18 ofthe control handle, as seen in Fig. 10, in which position of adjustmentthe cam 11 is locked with respect to the arm 52 and the control handleoccupies a telescoped compact position. This construction isparticularly advantageous in connection with lroners of the foldingcabinet type wherein it is desired to maintain a cabinet of minimumdimensions. In such instances this control handle may serve as aconvenient hand grasp for moving the ironer into and out of the cabinet,and when the ironer is in operating position outside of the cabinet thecontrol handle may be withdrawn upwardly to normal operating position,and when not in use may be telescoped to the position seen in Fig. 10.Furthermore, whenthe control handle is in telescoped position the knobportion thereof does not protrude appreciably above the shoe. This is ofparticular advantage in some instances when in ironing a piece offabric, the body thereof is thrown back over the shoe as it is fedbetween the fill roll and shoe, and hence the handle in such positionwill not interfere with proper training of the piece of fabric into thebight of the roll and shoe.

Although I have herein shown and described a preferred embodiment of myinvention, inanifestly it is capable of modification and rearrangementof parts without departing from the spirit and scope thereof. beunderstood as limiting this invention to the precise embodiment hereindisclosed, except as it may be so limited by the appended claims.
